WALTER MONTGOMERY AND GUSTAVE WEITI-IAS, 0F BROOKLYN, NEW YORK, ASSIGN-ORS OF ONE-THIRD TO EDWARD STAATS LUTHER, OF NEW YORK, N. Y.

AMALGAMATING APPARATUS.

To all whom it may concern:

Be it known that we, IVALTER MoN'rooai- ERY and GUSTAVE lVEiTHAs,citizens of the United States, and residing, respectively, at Brooklyn,in the county of Kings and State of New York, have invented certain newand useful Improvements in Amalgamating Apparatus, of which thefollowing is a specification.

The invention relates to improvements in apparatus for separatingprecious values from ore slimes and like materials.

In the following is described in connection with the accompanyingdrawings one embodiment of the invention, the features thereof beingmore particularly pointed out hereinafter in the claims.

In the drawings Figure 1 is a longitudinal sectional view of theapparatus; and Fig. 2 is a vertical sectional view on the lines AB ofFig. 1.

Similar characters of reference indicate similar parts throughout theseveral views.

In the drawings 1 and 2 indicate end frames supporting trough 3. Saidtrough 3 is mounted upon said end frames 1 and 2 by any suitable meanssuch as by plates 4 bolted to said end frames 1 and 2 as at 5. Saidtrough 3 is preferably circular in form and the bottom 6 thereof isdiagonally inclined, the object of said inclined surface being toprovide means for permitting the downward flow of liquids and materialsplaced therein. End frame or standard 1 supports hopper 7 which in turncommunicates with vertically set conveyer pipe 8 which in turn hasconnected therewith at its lower end a diagonally set conveyer tube 9.Said hopper 7 has associated therewith a feed chute 10 adapted to conveythe values and ore containing bodies from a suitable source of supply tosaid hopper 7.

11 indicates a water pipe feeding into hopper 7, the object of the samebeing to agitate the values while they are being fed into said hopper 7and at the same time to render the mass a semi-fluid.

12 indicates a shaft supported in bearing 13 at its upper end which hasmounted thereon a miter gear 14 meshing with gear 15 mounted on shaft16. Said shaft 16 has mounted on its outer end a sprocket. 17 carryingchain 18 which in turn engages sprocket 19 on intermediate shaft 20.Said shaft 12 has formed thereon a plurality of Specification of LettersPatent.

conveyer plates 21 adapted to convey the values in said conveyer tube 9.

22 indicates a shaft mounted in bearing 23 which is in turn bolted toend frame 1 as at 24. Said shaft 22 has mounted on its outer end a gear25 meshing with gear 26 mounted on drive shaft 27. Said drive shaft 27has mounted on its outer end a pulley 28 carrying belt 29 which receivesits power from any suitable source, such as from a driving pulley ormotor, said driving pulley or motor is not shown in the drawingsembodied in this application. Shaft 27 has mounted on its outer end asprocket 30 carrying chain 31 which in turn engages sprocket 32 onintermediate shaft 20. Said drive shaft 22 has formed thereon aplurality of conveyer plates 33 of the same diameter as the interiorwalls of conveyer tube 9. The conveyer plates 21, described as beingmounted on shaft 12, are also of the same diameter as the interior wallsof vertically mounted conveyer tube 8, the end of said conveyer plates21 practically contacting the outer periphery of conveyer plates 33illustrated in the drawings as at 34, the object of the same being toprovide a continuous conveyer from the hopper 7 to the discharge end 35of the ore feed. Said diagonally set conveyer tube 9 has formed thereina plural ity of holes or ports 36 adapted to permit the mercury 37 topass from trough 3 into said conveyer chute 9, whence it is forced tothe discharge end 35 by conveyer plates 33. 38 is a compartment formedat the end of said trough 3 and is adapted to receive the valuestogether with the mercury from conveyer tube 9 and trough 3.

39 indicates a controlling valve, the object of the same being toprovide means for drawing off the bulk of the values and mercury afterthey are separated from the slimes in said compartment 38.,

40 is an auxiliary compartment mounted directly above said compartment38 and has mounted thereon a chute 41 adapted to convey the overflowvalues and mercury to a trap 42 supported by bracket 43 which is in turnfastened to end frame 2 at 44. Said trap 42 has mounted thereinseparating head 45 mounted in such a manner as to form passages 46between the body of said retort 42 and a collector 47 Said trap 42 hasin turn mounted on its side thereof a chute 48 adapted to convey thewater and other waste products to any suitable source. Said collectorat? is mounted on nipple at) formed on the lower end of said trap t2 asat 50. Said collector l7 may be in the form of an auxiliary separatorfor the purpose of collecting the overflow material from which thevalues are extracted.

51 is a water pipe receiving a supply from any suitable source and isprovided with a jet 52 extending into compartment 38 as at 53, theobject of said jet being to provide means for thoroughly agitating thevalues after they have been thoroughly mixed with the mercury fromtrough 3. Said collector 47 has cut therein at its upper end, slightlybelow the separating head {5, a hole 52f communicating with water pipeconnection 55 which receives a supply of water through pipe connection56 from any suitable source of supply, the object of the same being topermit water jets to cleanse the values and mercury, permitting saidmercury to pass into the collector l7 and the water to ascend in saidtrap l2 and go to exhaust over chute 4-9.

The operation of the device is as follows: Sand and slimes containingthe values are fed into hopper 7 from chute l0 and conveyed downwardlythrough conveyer tube 8 to diagonally inclined conveyer tube 9. lVhilethe values are being conveyed through said tube 9, mercury from trough 3is permitted to enter said tube through ports 36 where it becomesthoroughly mixed with said values and is discharged through dischargeend 35 of said tube The overflow material containing water, values andmercury gradually ascends in compartments 38 and 40 and flows over chutell into trap -12. As soon as the mercury is fed into conveyer chute 9,the mercury will collect every particle of the values contained in theslimes and carry the same to said compartment 38 where the mercury andvalues, being heavier than the lighter substanceswater and sandwilldescend into the bottom thereof, the bulk of the values and mercurybeing drawn by means of draw off controlling valve 39; the lightersubstances, water and sand, overflowing said trap 42 and passingtherefrom over chute as to any suitable place of deposit, the overflowvalues and mercury being separated in trap 4-2 and collected bycollector 4E7. The mercury containing the values, as it is collected bymeans of collector l7, gradually accumulates until said collector ispractically filled. The values and mercury areretained by said collector4:7 and when practically filled are drawn off by means of valve a.

It is obvious that the device may be varied in many ways, particularlyin form, size and structural features, without departing from the spiritof the invention.

hat we claim and desire to secure by Letters Patent of the United Statesis 1. A device of the character described in cluding a supporting frame,a supply hopper mounted on said frame, a trough mounted on said frameprovided with a diagonally inclined bottom, a primary conveyer tubeassociated with said supply hopper, a secondary conveyer tube mounteddiagonally in said trough and cou'nnunicat-ing with said primary tube,conveyer blades mounted in each of said tubes, means for rotating saidconveyer blades, a mercury receptacle in said trough partially inclosingsaid secondary conveyer tube and communicating with the interiorthereof, a mixing compartment, a draw-oif valve mounted in saidcompartment, and water jetting means associated with said mixingcompartment for the purpose specified.

2. A device of the character described including a supporting frame, asupply hopper mounted thereon, a trough mounted on said frame, providedwith a diagonally inclined bottom, a primary conveyer tube associatedwith said supply hopper, a c-ylin drical secondary conveyer tube mountedin said trough, a mercury receptacle formed in said trough partiallysurrounding said secondary conveyer tube and communicating with theinterior thereof, a conveyer blade mounted in said primary conveyertube, a conveyer blade mounted in said secondary tube and mercuryreceptacle, means for rotating each of said conveyer blades from one ora common point, a mixing compartment, a valve associated with saidcompartment, and water jetting means mounted in said compartment for thepurpose specified.

In testimony whereof we have hereunto signed our names in the presenceof two subscribing witnesses.
